Performance of a 12-port handset antenna array operating in LTE bands 42/43 (3400-3800 MHz) and band 46 (5150-5925 MHz) is analyzed in XFdtd for varying hand hold positions on the device. The results computed include S-parameters, Gain, Efficiency and Envelope Correlation Coefficient.
The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. Wireless InSite’s diffuse scattering capability is based on Degli-Esposti’s work.
This example analyzes the coupling between four circular patch antennas mounted on the sides of a Boeing 757. The antennas transmit and receive at a frequency of 2.4 GHz. Coupling between each antenna is characterized using XGtd’s S-Parameter output, which can be displayed in the user interface or exported to a v1.1 Touchstone file.
